Alloy Design Workshop
2020: Damage-resistant steel design: Exploring the limits of metastability-engineering
Steels are by far the most commonly used structural alloys: worldwide, steel production reached 1808 million tons in 2018, which is more than all other metal production combined. Steels form the basis of the infrastructure of our most critical industries, from construction to automotive, packaging and energy. However, as a result, steel production and use also create the strongest impact on environment. Design efforts that enable steels to do more, with less, for longer, are required to address this challenge. To this end, an important concern is damage-susceptibility, which arises from the presence of multiple phases in steels, with different mechanical characteristics. Several opportunities exist through alloy and microstructure design, to control strain partitioning and localization tendencies in steels, and in turn, the damage micro-mechanisms. In this regard, metastability-assisted steels provide the greatest spectrum of possibilities, but also, the most complex scientific challenges. In the Alloy Design 2020 workshop, we will discuss the most recent ideas to push the limits of metastability-engineering, towards steels with superior damage resistance.The 2020 Alloy Design Workshop will be held on Dec. 4th, 2020.

2019: Micro-mechanics informed alloy design: overcoming scale-transition challenges
The last two decades witnessed the development of several micro- and nano-mechanical testing techniques. Simultaneously, there have been tremendous developments in electron microscopy detector technologies, full-field mapping techniques, and data analytics algorithms. These new tools and methods provide new insights regarding the mechanical behavior of metals. Initially, the research focus has specifically been on the fundamental mechanisms of plasticity, damage and fracture; and the role of size effects therein. More recently, more complex alloys with multiple phases, gradient structures or compositions, and hierarchical microstructures have also been explored with these tremendously improved tools. The fundamental question we would like to discuss in Alloy Design 2019 is whether it is possible to bridge the gap between the scales, utilizing what we learn at the nano- and micro-scale to guide alloy and microstructure design.
2018: New guidelines in alloy design: from atomistic simulations to combinatorial metallurgy
There is tremendous interest in the development of new metallic materials with improved property combinations. Fortunately, an enormous portion of the compositional space of metallic materials is virtually unexplored. In the last decade, introduction of compositionally-complex and high-entropy alloys created a widespread effort to explore this space more efficiently. Such efforts are further motivated by the development of additive manufacturing, severe plastic deformation, incremental forming and other advanced processing methods, which enable various new microstructures. This vastly-increased degree of freedom in metals design, calls for new guidelines. This workshop aims to initiate discussions on new approaches developed for this purpose. Presentations delivered by leading researchers in the field will follow this focused theme, covering a wide scope of approaches ranging from atomistic simulations to high-throughput combinatorial metallurgy methods.
2017: Sustainability through alloy design: challenges and opportunities
Metallic materials have enabled the vast majority of the key technological advances of the history of humankind. Going forward, our understanding of alloy design has the potential to help tackle critical sustainability challenges, by designing lighter-weight steels, formable magnesium alloys, fatigue-resistant aluminum alloys, repairable superalloys, and others. Yet, what is urgently needed is a comprehensive overview of the most urgent scientific questions in the design of metallic materials, to help orchestrate present efforts to address the most critical sustainability challenges. This focused workshop aims to identify the most important sustainability challenges and opportunities for each key metallic material, and discuss corresponding scientific research questions and current findings in a Gordon Conference style meeting. To trigger material specific discussions, world leading experts are invited to deliver overview talks on different classes of metallic materials. The presenters are invited also to join in as co-authors to a joint overview manuscript on alloy design, to be published in Progress in Materials Science.
